	Did a bunch of things to get dwc3/gadget.c compile in u-boot without build errors and warnings *) Changed the included header files to that used in u-boot. *) Used dma_alloc_coherent and dma_free_coherent APIs of u-boot *) removed sg support *) remove jiffies and used a simple while loop *) removed irq support and added a function to call these interrupt handler.
